摘要： A tool for attaching a support member formed with a hook member and a bendable tab member to a support post formed with a plurality of slots is disclosed. The tool is provided with a handle portion having an arcuate bending finger at one end and which is pivotally connected to a reaction finger having planar bearing surfaces. In use the reaction finger is placed in the slot in which the hook member is received and then the bending finger is inserted into the slot in which the tab member is received. Force is then applied to the handle portion which is applied to the tab member through the bending finger and which reacts through the reaction finger.

摘要： The invention disclosed herein relates to a fastener assembly and method of using same to preload a joint including a plurality of adjacent workpieces having aligned openings formed therein. The fastener assembly includes a pin member having an enlarged head and a shank located within the aligned openings in the workpieces and further includes a collar member having a deformable outer portion and a relatively hard inner portion located about a portion of the shank such that the inner portion is directly adjacent the shank portion. Also formed on the shank is a thread configuration adapted to cooperate with a complimentary thread configuration for snugging the workpieces together with a relatively light preload. After the joint has been snugged together, the collar member is crimped causing axial flow of material in the outer portion which reacts to stretch the pin member and induce a desired preload in the joint. Radial flow of the material in the outer portion is resisted by the hardened inner portion whereby the collar member does not flow into engagement with the shank portion of the pin member.

摘要： The invention disclosed herein relates to a tightening system including a wrench for applying torque to a fastener system. Associated with the wrench is a control system including measuring means for developing a first signal representative of the torque applied to the fastener. A second signal representative of a constant incremental time is introduced along with the torque signal into gradient calculating means which develops a signal representative of the slope of a torque-time curve which can be plotted for the particular fastener system being tightened. When the gradient signal falls to a predetermined percentage of the maximum previously stored gradient signal, at the yield point of the fastener system or some similarly significant point on the torque-time curve, a control signal is generated stopping the tightening of the fastener.

摘要： A fastener bushing for use in a panel structure consisting of a pair of spaced outer skins and a low density core therebetween is formed with an elongated shank adapted to be inserted through an opening in the panel. The shank has a longitudinal bore extending therethrough in which a fastener element can be inserted and includes an integral enlarged head formed at one end thereof which will overlie the skin along one side of the panel when the bushing is inserted in the openings. The bushing has a peripheral groove formed on the shank immediately below the head so that when the shank is fully inserted in the panel, the groove receives the edge of the opening through which the shank was inserted, thereby to positively retain the fastener bushing in the panel.

摘要： A sequential tightening system is disclosed in this application for tightening a plurality of fasteners to a final predetermined condition and includes a plurality of wrenches for tightening the fasteners and a control system operatively associated with each of said wrenches for tightening the fasteners to a first predetermined condition, preferably their seated condition and at a relatively high output speed of the wrenches, and temporarily discontinuing the tightening procedure. When the tightening procedure of all of the wrenches has been temporarily discontinued, the control means restarts the tightening procedure of each wrench simultaneously or, if desired, sequentially, and, preferably at a lower output speed of the wrenches. As each wrench tightens its operatively engaged fastener to the final predetermined condition, the control means discontinues the tightening procedure of that wrench.

摘要： A fastener for use in securing a stack of members together comprises a head adapted to be embedded in an outer surface of the stack and a shank adapted to extend through an aperture in the stack so that a tail projects beyond the other outer surface of the stack. As the head is embedded, material in the stack is displaced and develops residual compressive stresses around the hole in the vicinity of the head; as the tail is upset, the shank expands radially to provide an interference fit with the aperture and develops residual tensile stresses around the hole. In the vicinity of the head, these tensile stresses are superimposed upon the previously developed compressive stresses.

摘要： A prevailing torque fastener comprising an externally threaded shank having a locking portion comprising a displaced thread segment including an offset root and a correspondingly offset crest. When engaged with a mating internal thread, the locking portion causes the mating thread to deform at its minor diameter with little or no deformation at its pitch or major diameter.

摘要： A method and fastener assembly for preloading a joint wherein a pin having a shank and a head at one end is disposed with the shank portion passing through aligned apertures of a plurality of workpieces to be joined. The shank portion of the pin extends beyond the surface of the workpiece and is provided with an irregular surface configuration. A deformable collar having an initially smooth surfaced internal bore is disposed about the pin and snugged against the adjacent workpiece by a removably positioned means placed in abutting relationship against the free surface of the collar to lightly clamp the joint assembly together to remove free play in the joint. The collar is radially inwardly deformed by a crimping tool so that the initially smooth surfaced internal bore of the collar is deformed to assume a configuration complimentary to the irregular surface configuration of the pin shank and upon continual application of the crimping force an axial elongation of the collar and the shank of the pin is effected to provide a predetermined tension or preload on the joint assembly. After the collar has been deformed, the means to snug the joint together initially is removed.

摘要： A bracket clip to be secured to a vertical support post such as an H-post used in the construction of open shelving units. The clip is provided with a pair of extending tab members offset at an angle with the tabs adapted to be engaged in a trapezoidalshaped slot in the support post. The tabs of the clip are inserted in the slot in the support post while the clip is maintained at an angle and the clip is rotated to engage the tabs within the slot in the support post so that the tabs grip the post and securely fix the bracket clip to the post.
